` CHAIN-LINK ASSEMBLEE."

To all whornl t concern: Beitknown that LROLILYA. JOHNSON, a citizen ofthe United States; residing` at Los Angeles, in the county of LosAngeles and.

State of California, have invented new and .useful Improvements in*:Chain-Link Assem blers, of which the followingis a specification.

This invention relates to a hand tool for opening the end links oftransverse chains in antiskid chains for automobile wheels, and has forits object to provid-e a device that is substantial in construction,easily operable and so designed and constructed that by it the hook endlinks of transverse antiskid chains may have their eyes easily openedfrom the circumferential chain, and by which device other open eye linksor hooks can be readily applied in the renewal of the chain parts andquickly and securely closed. The invention consists of the construction,the combination and details an embodiment of which is illustrated in theaccompanying drawings and described and claimed herein.

Figure 1 is a plan view of the improved device with the handle beingbroken away and sectioned.

Fig. 2 is a side elevation of the device and showing in dotted lines theposition of link hooks to be opened and closed by the device.

In the illustrated form of the invention there is provided a base plate2 shown as oblong in plan and of suitable height, and at the forward endof the'base there is provided a pair of upwardly extending bearn inglugs 3--3 between which there is mounted the lower end of a lever 4which lower end is arranged on a transverse pivot bolt or other suitabledevice 5 extending through 'the bearing ears 3-3 and by which pivot thelever or handle 4 may be oscillated to and fro in the various operationsof the device.

The handle, which is `shown as broken away to indicate indenite lengthin Fig. 2, is provided with a hook 6 having its rearward end forked asat 7 to straddle the side faces of the lever 4 and this is mounted on atransverse pivot' bolt orv pin 8 passing through the handle. This hook 6is mounted adjacent the'lower end of the handle andy is normally thrownt0 an open position indicated in the drawing by a suitable meanscomprising, for instance, ak spring 9 one leaf of which is secured as atl10 to one face of the lower end of the lever yand the otherSpecification of Letters Patent.

end or leaf ofwhich lspriiig'extends out# wardly and engages thecontiguous kface of hook'vG.v n f kThe hook, hereinafter termed thepawl, can be pressed downwardly at will by suit able meansy as forinstance apushL rod 11 mounted in suitable guides 12, the rod ex tendingfrom adjacent the upper end of the lever et downwardly and having apart.

13 engaging the pawl 6 so that when the rod 11 is pressed downwardly bypressure on the button at its upper end the pawl `can be swung inwardlyagainst the action of the spring 9.

The device is especially adapted for the opening of the eyes 15 ofantiskid transverse chain links 16 one of such links being shown indotted lines as arranged at its lower end beyond a horn 17 projectingoutwardly from one end 0f the base`2 and over which the link 16 isstraddled with its upper ends f placed against the front inclined faceof the bearing part 3. When in such position the handle 4 may be thrownforwardly to the dotted line position and the pawl 6 pressed downwardlyto lock under thev overturned hook ends of the link 16 which form theeyes 15- When so engaged with the eye ends the lever is then pulledbackwardly and the nib of the pawl 6 will force open the eyes to suchdegree as may be necessary to `disengage therefrom the embraced sidelink indicated at 18. This enables the entire removal of a mutilatedtransverse chain which can be replaced by another, a part of which isshown in dotted lines at 20, and having the open eyes 21 at one end ofthe hook link 22 disposed on'each side ofan upwardly extending narrowiin 23 provided on the base 2 just in the rear of the bearing ears 3; sothat a heel 4 on the lower rear portion of the lever 4 can be swung downabout the pivot 5 and by pressure on the open eyes 21 close the same onthe inserted side chain indicated at 18.

From the above it will be seen that th y chain links, a lever fulcrumedon the base between said projections, e hook pivoted to said lever andadaptedto engage theA end portion of a link positioned on oneof theprojections and said lever havingy a project* ing 'portion thatisadepted t0 engage the end 'portion of a vchain link positioned on theother projection. i
